A proposal concerning the RequestUtils.populate()

[iloveyouwo]

Hi,
First of all, sorry for my poor english, but please read carefully.
I am a developer who use Struts for building RDBMS-based applications.
I have to make so many tables that is linked by PK-FK relation.
So There's so many Beans that are shaped like this
(ParentBean and ChildBean is linked by PK-FK)
============================================================
ParentBean.java
public class ParentBean {
 private int id;
 private String name;
 private ChildBean[] childBeans = new ChildBean[0];
 // get/set methods
 // ...
}
------------------------------------------------------------
ChildBean.java
public class ChildBean {
 private String childName;
 // get/set methods
 // ...
}
============================================================
ParentBean can have many, more than one ChildBeans, 
And I cannot guess how many ChildBeans would be created at run-time.
So this page that is used for user-input cannot be worked properly.

============================================================
ParentBeanInput.jsp
..
<html:text property="parentBean.childBeans[0].childName"/><br/>
<html:text property="parentBean.childBeans[1].childName"/><br/>
<html:text property="parentBean.childBeans[2].childName"/><br/>
<html:text property="parentBean.childBeans[3].childName"/>
..
============================================================
When request parameter is populated(when RequestUtils.populate() is 
called.),
Array IndexOutofBoundary Exception is occured 
Because Property Entities like parentBean.childBeans[3].childName does not 
exist.

So I use modified beanutils library that can extends length of arraies at 
run-time 
and make a component of array to populate this kind of request parameter 
that 
is mapped to array property of bean.

I would like to Form-Bean processor that support array of variable length.

Thank you for reading,Jang
